On classical and quantum liftings
L. Accardi, D. Chruściński, A. Kossakowski +2
We analyze the procedure of lifting in classical stochastic and quantum systems. It enables one to `lift' a state of a system into a state of `system+reservoir'. This procedure is…
Is Bell's theorem relevant to quantum mechanics? On locality and non-commuting observables
A. Matzkin
Bell's theorem is a statement by which averages obtained from specific types of statistical distributions must conform to a family of inequalities. These models, in accordance with…
Uniqueness of the EPR--chemeleon model
Luigi Accardi, Satoshi Uchiyama
A classical deterministic, reversible dynamical systems, reproducing the Einstein--Podolsky--Rosen (EPR) correlations in full respect of causality and locality and without the intr…
Chameleon effect, the range of values hypothesis and reproducing the EPR-Bohm correlations
Luigi Accardi, Andrei Khrennikov
We present a detailed analysis of assumptions that J. Bell used to show that local realism contradicts QM. We find that Bell's viewpoint on realism is nonphysical, because it impli…
A stochastic limit approach to the SAT problem
Luigi Accardi, Masanori Ohya
We propose a new approach to solve an NP complete problem by means of stochastic limit.
Dynamical detailed balance and local KMS condition for non-equilibrium states
Luigi Accardi, Kentaro Imafuku
The principle of detailed balance is at the basis of equilibrium physics and is equivalent to the Kubo-Martin-Schwinger (KMS) condition (under quite general assumptions). In the pr…
KMS States on the Square of White Noise Algebra
L. Accardi, G. G. Amosov, U. Franz
It was shown in [AFS00] that there are only three types of irreducible unitary representations theta of sl_2. Using the Schurmann triple one can associate with each theta a number…
On the physical meaning of the EPR--chameleon experiment
Luigi Accardi, Kentaro Imafuku, Massimo Regoli
The physical meaning of the EPR--chameleon experiment proposed in AcRe00b,AcRe01a, in which the EPR correlations are reproduced by local, independent, deterministic choices is re-e…
The EPR correlations and the chameleon effect
Luigi Accardi, Massimo Regoli
We describe an experiment in which two non communicating computers, starting from a common input in the form of sequences of pseudo--random numbers in the interval , and co…
Quantum stochastic equation for the low density limit
L. Accardi, A. N. Pechen, I. V. Volovich
A new derivation of quantum stochastic differential equation for the evolution operator in the low density limit is presented. We use the distribution approach and derive a new alg…
Quantum Boltzmann statistics in interacting systems
Luigi Accardi, Sergei Kozyrev
Collective operators that describe interaction of generic quantum system with discrete spectrum with a quantum field are investigated. These operators, considered as operators in t…
Interaction of 3-level atom with radiation
L. Accardi, K. Imafuku, S. V. Kozyrev
The interaction of 3-level system with a quantum field in a non-equilibrium state is considered. We describe a class of states of the quantum field for wich a stationary state driv…
A Generalization of Grover's Algorithm
Luigi Accardi, Ruben Sabbadini
We investigate the necessary and sufficient conditions in order that a unitary operator can amplify a pre-assigned component relative to a particular basis of a generic vector at t…
Non-locality and quantum theory: new experimental evidence
Luigi Accardi, Massimo Regoli
Starting from the late 60's many experiments have been performed to verify the violation Bell's inequality by Einstein-Podolsky-Rosen (EPR) type correlations. The idea of these exp…
Locality and Bell's inequality
Luigi Accardi, Massimo Regoli
We prove that the locality condition is irrelevant to Bell in equality. We check that the real origin of the Bell's inequality is the assumption of applicability of classical (Kolm…
Quantum decoherence and the Glauber dynamics from the Stochastic limit
L. Accardi, S. V. Kozyrev
The effects of decoherence for quantum system coupled with a bosonic field are investigated. An application of the stochastic golden rule shows that in the stochastic limit the dyn…
Teleportation of general quantum states
Luigi Accardi, Masanori Ohya
Quantum teleportation has been introduced by Benett et al. and dis cussed by a number of authors in the framework of the singlet state. Recentl y, a rigorous formulation of the tel…
On the structure of Markov flows
L. Accardi, S. V. Kozyrev
A new infinitesimal characterization of completely positive but not necessarily homomorphic Markov flows from a C^*-algebra to bounded operators on the boson Fock space over L^2(R)…
